Description

Hello 👋

I was looking through the documentation to look for a compatibility map between SPIRE and Kubernetes and came across two sources that seem little outdated.

  1. First is the Quickstart document which states:

The steps in this guide have been tested on these Kubernetes versions: 1.13.1, 1.12.4, and 1.10.12.

  1. Second is the Supported Integration.md which states:

The SPIRE project currently supports Kubernetes 1.18 through 1.21. Later versions may also work but are not explicitly exercised by integration tests.

Could someone please kindly point me to the up-to-date compatibility matrix. If there isn't one, I'm more than happy to help contribute and update both the sources mentioned above!
